There is a deference between being a grunt and being a fighter pilot. I have no problem with women pilots. However I think it is a very bad idea to allow women to serve in ground combat units.
I agree, and I think you and I would likely would agree that there is a spectrum of jobs, at one end we could say, yes...those are completely suitable for women in the military, and at the other end, we could say no...those are not.
In the middle is the gray area or line where the yes/no cleavage point occurs. That discussion does not appear to have taken place in a serious fashion, IMO.
